Hope this link works, if not I'll pay a screenshot of it.

Apparently (thanks for having me learn this ;) ) a kind of fellowships/fraternities based around a common year of birth were common around the turn of the century.

This medal commemorates that those born in 1880 now had turned 50, which was celebrated at a dinner in Stockholm.

(The article says that the engraver is “Carl Eldh”)

Hello Exo,
